因“内部”保护级别不可访问3

Question

我收到此错误“'removeCircleLabel'由于此行代码中的'内部'保护级别而无法访问。我将CVCalendar库添加到我的项目中。我添加了pod，但是当我在项目中添加视图控制器代码时，它给了我这个错误。

@IBOutlet weak var calendarView: CVCalendarView! 

    @IBAction func removeCircleAndDot(sender: AnyObject) { 
    if let dayView = selectedDay { 
     calendarView.contentController.removeCircleLabel(dayView)// **error on this line** 

     if dayView.date.day < randomNumberOfDotMarkersForDay.count { 
      randomNumberOfDotMarkersForDay[dayView.date.day] = 0 
     } 

     calendarView.contentController.refreshPresentedMonth() 
    } 
} 

public typealias ContentViewController = CVCalendarContentViewController 

public final class CVCalendarView: UIView { 
// MARK: - Public properties 
public var manager: Manager! 
public var appearance: Appearance! 
public var touchController: TouchController! 
public var coordinator: Coordinator! 
public var animator: Animator! 
public var contentController: ContentViewController! 
public var calendarMode: CalendarMode! 

public var (weekViewSize, dayViewSize): (CGSize?, CGSize?) 
} 


// MARK: Delete circle views (in effect refreshing the dayView circle) 
extension CVCalendarContentViewController { 
    func removeCircleLabel(_ dayView: CVCalendarDayView) { 
    for each in dayView.subviews { 
     if each is UILabel { 
      continue 
     } else if each is CVAuxiliaryView { 
      continue 
     } else { 
      each.removeFromSuperview() 
     } 
    } 
    } 
}

Answer 1

默认情况下，所有的方法，变量，常量等都是内部的。对于内部保护级别，这些方法，变量，常量等不能在模块外访问。

removeCircleLabel(:_)是日历模块的内部方法，您需要公开才能访问它。

也请阅读：What is the 'open' keyword in Swift? 这解释了何时应该使用public和open。

在我的快速搜索，我发现功能removeCircleLabel在CVCalendarContentViewController上GitHub。

// MARK: Delete circle views (in effect refreshing the dayView circle) 
extension CVCalendarContentViewController { 
    func removeCircleLabel(_ dayView: CVCalendarDayView) { 
     for each in dayView.subviews { 
      if each is UILabel { 
       continue 
      } else if each is CVAuxiliaryView { 
       continue 
      } else { 
       each.removeFromSuperview() 
      } 
     } 
    } 
} 

很明显，您可以从您的控制器访问此方法。没有保护。请检查您的日历查看来源与最新的一个。
